Love it, I have been using Henna for 40 years, I wanted to get an organic one, it gives a beautiful chestnut red tones, I have alot of grey hair, I apply it to well dampened clean hair, I then cover with freezer bag on my head and wrap with a towel, I leave on for 40 mins, no heaters, just let natural body warmth do the work, then wash off. Tips, put moisturiser on hair line to avoid skin staining, only use glass or ceramic to mix, dont use stainless steel, it deactivates the henna from colouring your hair, use a plastic spoon to mix, you can use copper coins to enhance red tones, I put mix in a plastic sauce bottle to apply to my hair, I comb hair into a ponytail ontop of my head, start at hair line, then just keep squeezing mix onto crown rub in, much easier, all the best.
